AERATOR COOLER FOR CREAM SEPARATORS.

Application filed June 1, 1926. Serial No. 112,962.

' provide a device of this nature which is thoroughly sanitary because of the washability thereof.

Another important object of the invention resides in the provision of a device of thls nature which will simultaneously cool the cream and aerate the same.

A still further important object of the invention is to provide a contrivance of this nature which is exceedingly simple in its 1 construction, efficient and reliable in use, in-.

expensive to manufacture, strong, durable, compact, convenient, and otherwise well adapted to the purpose for which it 18 designed. I v

A further object of the invention lies in the provision of a cone-shaped member having an inlet and outlet at its top so that water may be fed interiorly thereof for cooling the walls over which cream is adapted to be poured and'the provision of a trough at the bottom for catching said cream and pouring it into a suitable receptacle.

With the above and numerous other ob jects in view as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully describedand claimed.

In the drawing Figure 1 isan elevation of the contrivance embodying the features of this invention, and

Fig. 2 is a sectional view through the coneshaped member thereof.

Referring to the drawing in detail, it will be seen that I have illustrated in dotted lines, one of the numerous standard cream separators, which is provided with a pulley wheel indicated at 5 having, in the present instance, a belt 6 trained thereover. The aerating is accomplished by a draft of air drawn in through a screen box 7 outside of a building 8, within which the cream separator is disposed. This air passes through pipe 9. 7

A blower 10 is in communication with the inner end of the pipe 9 and blows the'air through a conductor pipe 11 which has its extremity curved downwardly as is indicated atv 12. A cone-shaped container 13 is constructed with a trough 14; exteriorly thereof and at the base thereof, and merging at a portion into an outlet spout 15. .An outlet pipe 16 has a coupling engaged with the apex of the cone-shaped container 18, and extends co-axially through the downwardly bent portion pipe 11.

An inlet pipe17 extends through the outlet pipe 16 and terminates adjacent the base of the cone container 13. This pipe 17 is con nected to any suitable source of water'sup ply so thatthe running water will run therethrough into the container 13 and exhaust out through the pipe 16.

The outlet spout 19 of the cream separator terminates adjacent the apex of "the cone-shaped container and allows the cream to flow on the exterior surface thereof, and it will thus be seen that the cone shapedwall of this container is cooled by the'water circulating therethrough so that the cream is cooled as it flows down the walls into the trough H and sin'iultaneously the cream is thoroughly aerated by the blast of air from the conductor pipe 11. r The cooling container 13 is very. easily detached for wash- 65 f 12 of the conductor 7 mg, because of its threaded engagen'ient with i the pipe 16 as is shown at 18. Thus the cone may be taken away and the exterior surface thoroughly washed.

It is just the outer surface of the cooling container that comes in contact with the cream, therefore, washability is one of the great advantages of this cooler. can'be used that cannot be thoroughly and easily was-shed. 1t is tached to any standard separator, requires very little extra power to run the blower fan, and easy hose connections may be made for cooling.

The device is eilicient, it will-lower the temperature of cream forty degrees. This is very necessary in the manufacture of sweet cream butter. The airing of the cream carries foul odors and flavors away. The air- No cooler] practical, can be ating of cream is the only way to remove unnow be clearly understood by those skilled in this art without a more detailed description thereof. The present embodiment ot the invention has been diicloeed in detail merely by way of example, since in actual practice it attains the i eatures of advantage enumerated as desirable in the staten'ient of the invention and the above description. It is apparent that numerous changes in the details oi? conetruction, and in the combination and arrangement oi parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacriiicing any of its advantages.

Having thus described my invention, what I claim as new is 2- l. in combination, a conductor pipe, a blower associat d with said conductor pipe, one terminal of the conductor pipe being directed downwardly, a water outlet pipe extending through the downwardly directed portion the conductor pipe co-axially therewith, a cone-shapnl container into which the lower end oi? the water exhaust i e is threadeth and a water intake pipe ending through the water outlet pipe into container terminating adjacent the bottom end thereof.

2. in combination, a cond ctor pipe, a blower associated with said conductor pipe, oneterniinal of the conductor pipe being directed downwardly, a water outlet pipe extendin through the dowinrardly directed portion of be coneuctor pipe co-axially therewith, a cone-shaped container into which the lower end of the water exhaust pipe is threaded, a water intake pipe extending through the 'ater outlet pipeinto the container terminating adjacent the bottom end thereof, and an annular trough formed on the base of the container exter1- orly thereof and merging at a portion into a spout.

b. in con'ibination, a conductor pipe, a blower associated with said conductor pipe, one terminal. of the conductor pipe being dirented downwardly, a water outlet pipe ex tending through the downwardly directed portion of the conductor pipe co-axially therewith, a coneshaped container into which the lower end of the water exhaust pipe is threaded, a water intake pipe extend 112g through the water outletpipe into the container terminating adjacent the bottom end thereof, a pipe leading into the blower and having a feed box at its intake terminal.

i. in. LOlnlJlhRlLlOIl, a cone-shaped container, "ie apex of the container being ope and interaily threaded, a flange formed on i about the base of the container and a portion into a spent, a wat r out pipe threaded into the apex and a water intal-ze pipe ezdending l the outlet pipe into the container and terminating a distance from the bottom thereof.
